“…Isopentane has the least exergy damage, while R123 achieves the first and second rules' maximum efficiency. Acar and Arslan [15] presented energy and exergy analysis of the organic resin cycle with solar energy and geothermal energy. Their results showed that the proposed system's energy output will be around 305 to 713 kWh.…”

“…It can depict each parameter's effects on the system and evaluate the system economically [24][25][26]. Merve [15] studied a solar-and geothermal energy-powered Organic Rankine Cycle (ORC) based on the first and second thermodynamics laws and showed that while the total power extracted by the solar system is increased, energy and exergy efficiencies of the geothermal-powered ORC decreased. Iqra [27] used the exergy analysis for a solar bakery unit and found out that the exergy efficiency is about 59.26%.…”

The combined heating and power (CHP) system is among the most effective ways to increase energy and exergy efficiencies, reduce fuel consumption, and reduce operational costs. In this study, the combination of an electricity and heat CHP system with the prime movers of a gas turbine and a horizontal axis wind turbine under the strategy of providing electric charge has been investigated. This study aims to evaluate the effect of the wind turbine on the system. The Blade Element Momentum Theory (BEM) is used to model the wind turbine under different wind speeds, pitch angle, and tip speed ratios to show their effect on the gas turbine system under different combustion chamber temperatures and pressure ratios. The results show that the proposed CHP system has significant advantages over the separate production system. It is shown that the best operating condition for the wind turbine is at the wind speed of 12 m/s, the pitch angle of 5°, and the tip speed ratio of 3. Moreover, the wind speed and tip speed ratio effects become considerable at the high-pressure ratios of more than ten and the combustion chamber temperature below 1250°C on the total system's exergy efficiency. Also, compared to the separate production mode, operational costs and fuel consumption are reduced by about 55% and 60%, respectively. Finally, taking into account the interest rate, the payback period will be equal to 5.4 years.

“…However, recent years have seen significant interest in TES systems, and efforts were made to reduce costs and improve performance by focusing on technologies with local experience and keeping systems as simple as possible. Various studies have addressed technical issues and evaluated the potential for new TES systems, focusing on performance and optimization, design, simulations, applications, and thermal and transport phenomena analyses (including thermodynamics, heat transfer, and mass transfer) [11,51,61,98,[100][101][102][103][104][105][106][107][108].…”

“…Ocean energy, another renewable source, is also examined in combination with both sensible and latent TES systems [16,94,145]. Some studies investigate hybrid renewable energy systems incorporating multiple renewable sources, such as solar-geothermal, ocean-solar, and solar-wind-ocean systems [105,107,112,114,146,147]. These hybrid systems typically involve sensible or latent TES to optimize the combined use of different renewable resources.…”

Current industrial civilization relies on conventional energy sources and utilizes large and inefficient energy conversion systems. Increasing concerns regarding conventional fuel supplies and their environmental impacts (including greenhouse gas emissions, which contribute to climate change) have promoted the importance of renewable energy (RE) sources for generating electricity and heat. This comprehensive review investigates integrating renewable energy sources (RES) with thermal energy storage (TES) systems, focusing on recent advancements and innovative approaches. Various RES (including solar, wind, geothermal, and ocean energy sources) are integrated with TES technologies such as sensible and latent TES systems. This review highlights the advantages and challenges of integrating RES and TES systems, emphasizing the importance of hybridizing multiple renewable energy sources to compensate for their deficiencies. Valuable outputs from these integrated systems (such as hydrogen production, electric power and freshwater) are discussed. The overall significance of RES–TES hybrid systems in addressing global energy demand and resource challenges is emphasized, demonstrating their potential to substitute fossil-fuel sources. This review provides a thorough understanding of the current state of RES–TES integration and offers insights into future developments in optimizing the utilization of renewable energy sources.
